In the slideshare presentation Journalism 2.0: Social Media Ethics, Nathan T. Wright gives some cues on how to judge and work with sources from social media. This subject is actual as in this kind of cicumstances, social media give often more information. Think of the revolts in Egypt, the news about the Christmas lights at Harrod’s in London, plane crashes and other accidents. The reliability of the sources need checking, probably even more then usual. The challenge is often to find the right person who is a source, place the message in context of what happened. Checking twice or more often is the rule here. Nathan gives some useful handles, also on how to judge images that may be manipulated.
